Radoslaw, All of the software is you mentioned is optional. The only software that is required for External Storage on the USP or NSC is the Universal Volume Manager (UVM) Software.
Also, I don't think it is correct to say that all of the software is all charged at Enterprise price across the board. Some software that delivers Enterprise Storage functions for cheap disk is charged at Enterprise price (e.g. TrueCopy), but there is other Software that uses a Tiered Pricing Model (e.g. Tuning Manager). I think of software like TrueCopy in the same way as a good quality spanner - the tool costs the same price whether you use it on a Mercedes or lawnmower. I'm not sure how buying minus "n" boxes is going to make cheaper replacement for TrueCopy and Shadowimage compared to using UVM, as you are still going to have to buy the licensed software for those boxes in order to have those features. For example, if you want to do something like FlashCopy from your current storage to some minus "n" boxes you will have to buy FDR/PAS or TDMF, or buy a Remote Copy licence if both boxes are from the same vendor. I'm just picturing how much floor space and power it would take to store 10TB of data in a 10 year old EMC 5500 or HDS 7700C, compared to a few drawers of SATA storage using 400GB drives. My fading memory seems to recall that a 7700 classic could hold about 720GB, so you would need 15 fully configured boxes to hold 10TB. I mention the 7700 classic because I seem to recall that you are using 7700 and 7700E for ML2 data. If you had a USP or NSC, then these could be replaced with some cheap SATA drives, and the only software you would need is UVM, where UVM is based on External TB only. In most cases there would be some TCO savings in floor space, environmentals and Maintenance costs, but we know this varies from site to site and country to country - YMMV. BTW, how does TrueCopy pricing compare with VTS P2P, including the CX1 units in both sites? Ron > > SATA drives attached to mainframe looks veeeery good ...unless you see > the prices...
